LOAD-DUMPING APPARATUS.

S?ECIFICATION forming part of Letters Patent No. 561,485, dated June 2,1896.

Application filed August 9,1895. fierial No. 558,728. (No model.)

To all whom, it may concern:

Be it known that I, TIMOTHY CARROLL, a citizen of the United States,residing at Anaheim, in the county of Orange and State of California,have invented a new and useful Load-Dumping Apparatus, of which thefollowing is a specification.

In Southern California the raising and shipping of beets formanufacturing sugar re quires the rapid unloading of large numbers ofwagon-loads of beets, for the reason that the boots must be weighed andsampled by the sugar-manufaeturers, and it is impracticable to unloadexcept at the place where the sampling is done, because the samples mustbe taken at the time of unloading each load in order to get a fairaverage of each load. In order to handle these beets it has heretoforebeen customary to place a net in the wagonbed and to then load the beetsupon the net, and at the place of unloading the not was lifted by aderrick and the load drawn out of the wagon and brought over the car andone side of the net then released; but this system was not sufficientlyrapid, and great inconvenience and delay resulted, it frequentlyoccurring that thirty teamsters would have to leave their wagons loadedall night and wait their turn next morning to unload.

One object of my invention is to avoid all this inconvenience and lossof time, and to provide means whereby a farm-wagon loaded with beets canbe dumped in a very short period of time.

With my invention as high as twenty-seven wagon-loads of beets, weighingin the aggregate nearly forty tons, have been dumped from one dump intorailroad-cars, thus loading two cars, in thirty minutes. The actual Workof dumping a four-horse-wagon load of five tons can be done easily inhalf a minute. In practice I have found thirty seconds to be sutlicientfor dumping the load after the wagon has stopped in place on thedumpplatform.

My invention relates more particularly to the appliances andcombinations of parts by which I am enabled to so rapidly unload heavyand light wagons loaded with beets.

It is very important that the apparatus shall work rapidly, that theteam remain hitched to the wagon during the dumping,

that the apparatus be so constructed and arranged that the wagon can bejolted, if required, to jar loose any beets that do not readily slideout of the wagon-bed, and that the parts be so arranged that the wagoncan .be easily and quickly put into shape to be driven away as soon asthe load is dumped. A further and very important consideration is to soconstruct and arrange the apparatus as to avoid any injurious strain onthe Wagon, and a peculiar and valuable feature of my invention is that Idump the load sidewise and fasten the vehicle to the tilting support bya chain or other suitable tie extending between and fastened to thetilting support and the bed of the vehicle. By this feature I make itpossible to rapidly dump the load and not rack the wagon. In fact, byreason of this arrangement, the operation of dumping a load from a wagondoes not rack or strain the vehicle in any part except that strain comesupon that part of the bed to which the chain is fastened, and that partof the bed can easily be made strong enough to withstand the strain. Nosevere strain comes on the running-gear, and this is of greatimportance. So far as I am aware, in all other appliances proposed fordumping-wagons the vehicle is to be held by the running-gear, and suchappliances are not adapted for the work which my apparatus does.

It is an object of my invention to accomplish the desired Work ofunloading wagonloads of beets as above stated, and to do it withoutstraining or rackin g the wagon. This I have fully accomplished by myinvention.

My invention is also applicable for dumping car-loads of beets and isalso adapted for dumping from cars, wagons, and other vehiclesbulk-loads, such as coal, corn, &c., in loading vessels and for otherpurposes.

My invention comprises the combination of a tilting vehicle-support forthe loaded vehicle, pivoted longitudinally to tilt sidewise, alongitudinal axis upon which the vehicle-support is pivoted, meansfastened to the tilting support and to the bed of the vehicle forholding the vehicle on the vehicle-support, a lever for tilting thevehicle-support sidewise and returning it to its horizontal position, ateamsupport at the front of the vehicle-support, on which the team canstand hitched to the vehicle while it is dumping, and a stop arranged tostop the tilting support on a slant and prevent it from tilting farenough to materially interfere with the team hitched to the Vehicle. Italso includes the vehicle-support and various parts and combinations ofparts hereinafter more fully specified.

My invention also comprises the combination of a vehicle-supportarranged to tilt sidewise, a vehicle having a bed provided with a hingedside and adapted and arranged to allow its load to be dumped offsidewise, and means extending between and fastened to the tiltingsupport and the vehicle-bed for holding the vehicle on thevehicle-support when it is tilted, a lever fastened to and projectingfrom the side of the tilting support opposite that toward which thesupport tilts, and the stop arranged to stop the support when it hastipped sufficiently to cause the load to slide off sidewise. This isapplicable either for railway-cars, wagons, sleds, or any vehicle havinga bed from which a load can slide sidewise when the vehicle is tipped.

A distinctive feature of my invention as applied to wagons is the hingedside of the bed arranged wholly above the wheels and the dumping of thevehicle sidewise and stopping the tilting support on an incline and thusdumping a large load Without the necessity of unhitching the team, forby this means I avoid all the necessity of backing and of all other slowor complicated ways or means for dumping the load, which are necessaryand which consume time in the case of wagons that dump endwise. Bytilting the wagon sidewise I have made it much easier, quicker, and lessexpensive to unload the loads than is possible by any other meansheretofore known. The driver of the team can drive across the tiltingsupport and stop with his team upon the team-support, and the dumpmancan then dump the load while the team is hitched thereto, and theteamster can then drive on at once, so that there is but little stoppageof the team to dump the load.

In carrying out my invention for dumping a wagon-load of beets I raisethe wagon-bed above the wheels or arch the floor over the hind wheels,and I provide the wagon-bed with a drop side and provide such drop sidewholly above the wheels with supports to hold it extended from the bedwhen dropped, so thatthe drop side serves as an apron to shoot the loadonto the stationary apron which is provided at the side of the dump toshoot the load into the car.

The accompanying drawings illustrate my invention.

A indicates a vehicle support or platform pivoted to tilt sidewise.

' B indicates an axle arranged longitudinally underneath such support,which is thus piv otally mounted so that it can be tilted sidewise.

0 indicates a supporting-stop against which one side of the vehicle-s11pport rests when the platform is not tilted.

D indicates a stop upon which the other side of the tiltingvehicle-support rests when tilted. Such support is preferably soarranged on its axle that its weight will hold it in its level position,and preferably the tilting support is sufliciently overbalanced to holdit from tilting when an unloaded wagon is driven upon it along the trackA, which is provided thereupon for the vehicle; but is not sufficientlyoverbalanced to hold it from tilting when a loaded wagon is driven onthe track A, which is located with its mid-line between the axle and thedump edge a of the tilting support, so that when a loaded wagon is uponthe support the weight of the wagon will overbalance the support in theother direction and tend to tip the support toward the dump side.

A indicates a wheel-guide and stop-rail against which the wheels on oneside of the vehicle may engage when the vehicle is upon the support.

A indicates suitable means 011 the opposite side of the wagon forholding the wagon firmly upon the track.

A indicates a lever projecting from the upper side of thevehicle-support that is, the side from which the wagon dumps. This leveris designed for tipping and returning the support.

A indicates a pin or other suitable fastening for holding the lever inits depressed position, thus to prevent the tilting vehicle support orplatform from prematurely tipping when the wagon is driven thereupon.

E indicates the approach to the tilting IIO platform, and F indicatesthe team-support or platform upon which the team stands while the wagonis being dumped.

G indicates the wagon, the running-gears of which are the same as thatof any ordinary wagon. The bed G is provided with a smooth bottom G andwith a hinged side G.

g, g, and g indicate latches which engage the hinged side when it israised and hold it in place. These several latches hook down upon thetop of the hinged drop side G, and when they are lifted they releasesuch side and allow it to drop out and down. It is desirable that thedrop side shall not drop until the wagon is sufficiently tipped to allowthe beets to run out upon the apron II, which is provided at the side ofthe frame I of the machine. The middle latch g is sufficient to hold thedrop side while the wagon is standing upon the dump, and in practice thetwo end latches g g" are released from the side before the platform istipped, and I provide automatic means for releasing the other latch atthe proper time. Such means consists of a line, rope, chain, or cord J,which is held above the wagon and is hooked into an eye g on the freeend of the latch g and is so adjusted that when the wagon is tippedsufficiently to allow the beets to discharge from the drop side G ontothe apron H the latch will be withdrawn from the drop side and thusrelease it. The line-support which I have shown in the drawings consistsof uprights K K and braces K K and a pulley 7d, located substantiallyvertically above the place where the middle latch will come when thewagon is brought to a stand upon the platform.

In my first machine, which I built and used at Anaheim in the month ofAugust, 1894, the latch-drawing rope J was led directly over the uprightK, and this operates to draw the latch more satisfactorily than when.the rope is supported more nearly over the end of the latch, but is notso convenient for hitching to the latch.

The means for holding the wagon upon the platform consist of a chain A,fastened to the platform at the upper edge thereof and provided at oneend with one or more large links 1, adapted to hook upon a coil-hook 2,which is fastened to the wagon-bed. The chain is preferably adjustablyattached to the tilting support, so that it can be moved along thesupport to bring it to the middle of the wagon.

3 indicates a slide-bar fixed to the tilt-support, and the chain islooped around such slide-bar and the loop is adj ustably fastened by agrip-link at, by means of which the slack of chain between the wagon andthe tilting support can be taken up after the large link has been hookedover the coil-hook 2. The coil-hook is fasten ed to the frame of thewagonbed and extends downward therefrom and curves downward, inward,upward, and outward, so that when the chain is hooked thereupon therewill be no danger of its becoming released when the wagon is tilted. Theguiderail A will hold the wheel of the wagon if the wagon should slipupon the platform, but ordinarily when the chain has been properlytightened the wagon will dump without slipping. Sometimes the driverwill drive the wheels against the rail A, but it is not necessary to doso. Care should be taken to draw the chain taut before the wagon isdumped, in order that there may be no jerk-- ing upon the chain, whichis liable to break the hook. The hook, the portion of the bed to whichit is fixed, the chain, and the slidebar must be strong, so as to standthe strain.

My invention is applicable for use at a railway-station for loading carsor it can be used at the factory for dumping the cars, and the dump canbe made portable, if desired, as shown in Fig. 10, so as to be drawn todifferent places in the factory or on jetties or wharfs, where it may bedesirable to change the place of dumping. In the portable device theframework 1 which supports the tilting vehicle-support and the approachand the team-support is mounted on wheels or rollers R.

S indicates a capstan for drawing the apparatus from place to place.

In order to make the wagon-dump tilt more easily, the top of the tiltingsupport is raised at the upper side, as shown at 5, Figs. 1, 2, and 3,so that when the wagon stands upon the tilting support it is tiltedtoward the dumping side. The difference in level of the lower and uppersides of the track should be three or four inches.

6 indicates a counterweight on the upper side of the tilting support toassist in returning the support and the empty wagon to the uprightposition after the load has been dumped. The lever A is provided with arope 7, by which it can be pulled down after the load has been dumped.

M indicates a railway-car for receiving the load, and O a railway-track.

P is a platform for the workmen who operate the lever A. Thelatch-operating rope orline J is led over suitable pulleys 7c and 7c,and a belaying-pin 8 is provided for fastening the same.

9 indicates a chock-block for checking the front Wheel of the wagon whenthe wagon has reached the proper place upon the platform.

f indicates a wheel-guide on the team-support to guide the wheels whenthe wagon is driven off of the tilting support.

6 indicates a guide-rail on the approach, and 6 indicates a raise on theupper side of the track to lift the wagon-wheel to the height of theupper side of the track on the tilting support.

The pivot or axle B upon which the tilting support is mounted may bemade of one or more joints of gas-pipe or a straight rod or any othersuitable device for pivoting, and

the support may be fastened to the axle by bands I), and the axle may befastened to the framework 10, which supports the tilting support.

Q indicates a apron II. 7

Suitable means are provided for holding the end latches g g uppreparatory to dumping the load. In Fig. 8 a leg or catch 11 is shownpivoted to the latch, so as to drop into place and rest 011 the top ofthe end board of the bed G2 when the latch is lifted.

I will now describe the operation of dumping a five-ton load of beetsfrom a wagon.

The wagon is driven up the approach E and onto the tilting support A,and when it has reached the proper place the attendant places thechock-block 9 in front of one of the front wheels, preferably the one onthe upper side, so that the tongue will be thrown slightly in thatdirection by the turning of the front axle. Then the teamster dismountsfrom the wagon, the end latches g g are raised from the drop side andare held up by the catches 11, which swing down and rest on theend-boards, respectively, of the bed, and then the line J is rope forhandling the hooked into the eye of the middle latch g.

One of the large links 1 of the chain A is slid along the slide-baruntil it is even with the coil-hook on the wagon, and then one of thelarge links of the chain is hooked upon 3 the coil-hook and the slack isthen taken up j by means of the grip-link, which is slid up: the smallpart of the chain until the chain is 1 The pin A is then withdrawn andthe weight of the loaded wagon will tip j the tilting support, and asthe wagon tilts the line J holds the latch from following the drop sideof the wagon, and the drop side is redrawn taut.

leased and the load discharges over the same and over the apron I-I intothe car. The stop D prevents the support from tilting too far, I andwhen the load is discharged the attendants pull the lever A intothehorizontal posit-ion and replace the pin above it. If from any cause thebeets do not readily dump, the lever can be worked up and down until theload is shaken out of the wagon. The platform will strike upon the stopD and thus jar the wagon to release the beets that may have stuck. Themovement of the wagon-tongue is very slight and is not sufficient tointerfere with the horses. As soon as the wagon has been righted thedrop side is raised into place and the end latches are dropped intoplace,

tively connected with the windlass by ropes V V, one of which is woundupon the windlass in one direction, while the other is wound uponthewindlass in the other direction, so that the rotation of the Windlassin one di rection will wind the rope which leads from the lower arm ofthe lever and will pull the lower arm of the lever up and at the sametime will unwind the rope which leads to the upper arm of the lever tothus release the up per arm, and the reverse movement of the Windlasswill pull the upper lever down and release the lower one. 3y this meansthe car can be easily handled.

G" indicates sills between the axles and the wagon-bed to raise thewagon-bed above the hind wheels, thus to allow the load to slide offover the Wheels.

I have not illustrated the form of wagonbed in which the floor is archedover the hind wheels, as that will readily be understood by anymechanic. The arch should extend from side to side of the bed, thepurpose being to avoid any projections which would hold the load fromslipping off sidewise.

Now, having described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination of a vehicle-support arranged to tilt sidewise; meansfor tilting the support and returning it to a level position; a stoparranged to stop the support on a slant; a vehicle having a bed providedwith a drop side wholly above the wheels and adapted to allowits load tobe dumped off sidewise; means extending between and fastened to thetilting support and the vehiclebed for holding the vehicle on thevehiclesupport when it is'tilted; a latch for holding the drop side inplace and adapted to be released when the wagon is tilted; and means forsupporting the drop side when it is dropped.
